I've been taking the 50% caps from another place. They offer 500mg caps so it's easy for me, which is the bottom line. I would just prefer to spend my $$$ with my extended Np family. Bummer about the PLCAR, though. I hope something opens up.

Essentially, all carnitine forms enhance the mitochondrial use of fatty acids. The advanced forms of L-Carnitine, namely, Acetyl-L-Carnitine, Propionyl-L-Carnitine, and Acetyl-L-Carnitine Arginate, are significantly more potent than simple L-Carnitine in terms of fat-loss and anti-aging benefits.

Propionyl-L-carnitine is a form of carnitine that has a special affinity for heart muscles, producing potent effects in cardiac and skeletal muscle, producing significant improvements in energy and stamina. Dosage recommendation is around 1 000mg daily.

Combining the two should produce excellent results. If your budget does not permit this, you might prefer a combination of base L-Carnitine and ALCAR (PLCAR has its key benefit in the cardiovascular realm).

As you know, ALA co-supplementation is a must, as Alpha Lipoic acid turns out to be a natural co-factor for a mitochondrial enzyme crucial in the break down of fatty acids. This enhances cellular energy efficiency. Furthermore, lipoic acid is a powerful antioxidant that enhances intracellular levels of vitamin C and glutathione, powerful antioxidants on their own.

I take ALCAR, love it, and have tried DCP and had noticed considerable endurance gains so count me in for someone who would buy the bulk PLCAR---One question though: How is PLCAR when taken without caps? I have no problem with ALCAR and others so I'd imagine PLCAR would go down fine too.

Also, I would be interested in trying other Carnitine combinations to see if any noticeable differences are present

--> (especially this one) L-Carnitine-Arginate and L-Carnitine-Tartarate and L-Carnitine-Fumarate
